Polled Input Implementation

Shared Code
#1 
public class Input implements KeyListener, MouseMotionListener, MouseListener {
	private HashMap<Integer, Inputs> inputs = new HashMap<Integer, Inputs>();
	public int mouseX, mouseY;

	public void update() {
		for (Map.Entry<Integer, Inputs> entry : inputs.entrySet()){
			entry.getValue().update();
		}
	}

	public boolean isDown(int keyCode) {
		Inputs input = inputs.get(keyCode);
		if(input != null){
			return input.isDown;
		}
		else return false;
	}

	public boolean isClicked(int keyCode) {
		Inputs input = inputs.get(keyCode);
		if(input != null){
			return input.isClicked;
		}
		else return false;
	}

	public void keyPressed(KeyEvent ke) {
		int keyCode = ke.getKeyCode();
		if(!inputs.containsKey(keyCode)){
			Inputs input = new Inputs();
			input.toggle(true);
			inputs.put(keyCode, input);
		}
		else inputs.get(keyCode).toggle(true);
	}

	public void keyReleased(KeyEvent ke) {
		inputs.get(ke.getKeyCode()).toggle(false);
	}

	public void mousePressed(MouseEvent mo) {
		int mouseCode = mo.getButton();
		if(!inputs.containsKey(mouseCode)){
			Inputs input = new Inputs();
			input.toggle(true);
			inputs.put(mouseCode, input);
		}
		else inputs.get(mouseCode).toggle(true);
	}

	public void mouseReleased(MouseEvent mo) {
		inputs.get(mo.getButton()).toggle(false);
	}

	public void mouseMoved(MouseEvent arg0) {
		mouseX = arg0.getX() / Engine.SCALE;
		mouseY = arg0.getY() / Engine.SCALE;
	}

	public void keyTyped(KeyEvent ke) {
	}

	public void mouseClicked(MouseEvent arg0) {

	}

	public void mouseEntered(MouseEvent arg0) {

	}

	public void mouseExited(MouseEvent arg0) {

	}

	public void mouseDragged(MouseEvent arg0) {

	}

	public class Inputs {
		private int presses, absorbs;
		public boolean isDown, isClicked;

		public void toggle(boolean pressed) {
			if(pressed != isDown) isDown = pressed;
			if(pressed) presses++;
		}

		public void update() {
			if(absorbs < presses){
				absorbs++;
				isClicked = true;
			}
			else isClicked = false;
		}
	}
}

So I’ve experimented in different implementations of getting input from the user. This current implementation allows me to poll for constant input and also achieve a psuedo event system with the isClicked method. Also, with the addition of a hash map, I can check for any java KeyEvent or MouseEvent very quickly. Is there anything else that can be improved? I’ve been through many implementations, adding on what I learn over time, and I’ll be glad to take any advice.
